The HID Signo Keypad Reader 40K is a founding member of the Signo platform.

Offering a truly dynamic approach to secure electronic access control, HID Signo Readers are designed to be highly versatile, powerful, and connected for the future.

A perfect fit for multi-factor authentication door applications requiring a narrow keypad reader, the HID Signo Keypad Reader 40K supports an unparalleled range of different credential technologies in a variety of form factors including cards, fobs and mobile devices.

Key Features:

Highly Versatile — Support for the widest range of credential technologies, including HID Mobile Access via native Bluetooth® and Near Field Communication (NFC) capability. Also features Apple’s Enhanced Contactless Polling (ECP) to support credentials in the Apple Wallet.

Enhanced Performance — Storage of cryptographic keys on certified secure element hardware, plus a new surface detection feature that allows the reader to automatically recalibrate and optimize read range performance

Connected to the Future — All readers include out-of-the-box support for Open Supervised Device Protocol (OSDP) for secure bidirectional communication. Each reader is also designed to be connected and managed remotely without “sneakernet” or the need to be physically touched.

Moreover, HID Signo Readers are simple to order and install, making the upgrade process easy
